What is AWS Architecture?

AWS architecture refers to the structural design that governs how cloud services and resources interact, scale, and integrate within Amazon Web Services. It provides the blueprint for deploying infrastructure, building systems, and managing workloads. This is vital for both greenfield projects, where architecture is created from scratch, and brownfield scenarios involving the review or refactoring of existing environments. A well-thought-out AWS architecture supports operational efficiency, scalability, compliance, and speed of delivery.

Why Architecture Matters in AWS
Without careful AWS architecture design, businesses often experience spiralling cloud costs, performance bottlenecks, and gaps in security posture. Poor architecture leads to fragmented infrastructure, limited visibility, and unpredictable scalability. By contrast, good architecture delivers measurable benefits. These include cost control through rightsizing and scheduling, robust data protection via AWS security best practices, and the ability to scale quickly without rearchitecting core systems. Using the AWS Well-Architected Framework as a guide, we focus on building secure, high-performing, resilient, and efficient cloud systems.
Our AWS Architecture Services
Our AWS architecture consultancy is tailored to meet organisations at every stage of their cloud journey. Whether you're starting from scratch or looking to improve what’s already in place, our services include:
- AWS architecture design for new applications and workloads.
- Comprehensive cloud infrastructure reviews, measured against the AWS Well-Architected Framework.
- AWS cost optimisation through usage analysis and rightsizing strategies.
- Security and compliance assessments focused on industry standards and AWS security best practices.
- Design and implementation of high availability and failover architectures.
- Multi-account strategies, including Landing Zone configuration and ongoing governance support.
How We Work with You
We begin with discovery to understand your current architecture, objectives, and constraints. This informs our collaborative planning process, where we work closely with your technical teams to produce visual architecture diagrams, supporting documentation, and technical artefacts. Our process includes feedback loops to ensure alignment and clarity before anything is deployed.
We use proven tools and methodologies, including the AWS Well-Architected Tool, CloudFormation, AWS CDK and Terraform. We also integrate with your existing CI/CD pipelines and monitoring systems, ensuring new designs are production-ready and future-proof. Our emphasis on observability frameworks helps maintain performance visibility across your entire AWS environment.

Case Study: From Costly Cloud to Lean Architecture
A financial services provider approached D55 with concerns about escalating AWS costs and infrastructure complexity. Following a detailed cloud infrastructure review, we redesigned their AWS cloud architecture to introduce automation, improve scaling logic, and apply tighter cost governance. As a result, they reduced cloud expenditure by 32% within six months, improved system resilience, and achieved audit-ready security standards.

What our Clients Say

“While we led the initial business scoping and discussions with key stakeholders, it was a very smooth process working the D55 team to expand on this vision. The D55 team took ownership of building the solution and worked closely with us throughout the process. The quality of the work, combined with the excellent support during the handover, is exactly what we value in a partner.”

D55 enabled us to migrate from on-premise to a cloud-based solution, resulting in monthly cost savings of about 40%. Cloud-based systems give us a high level of resiliency and an unlimited capacity to scale. We’ve really put in place the foundations for later phases of work and further cost reduction as we scale. It was a partnership as opposed to a service - we work well together.
